Abstract
Apparatus and a process for electroylic recovery of silver from fixing baths obtained by development of photographic films wherein the fixing bath solution coming from the tank for the fixing bath to the development apparatus is fed from the development apparatus into one chamber in a recovery apparatus comprising two chambers until the said first chamber is filled whereupon the silver precipitation is started in the said chamber; an automatic redirection of the liquid flow from the development apparatus to the second chamber of the recovery apparatus is made to the said second chamber which being filled with liquid during the precipitation process in the first chamber. After concluded silver precipitation in the first chamber the liquid treated therein is automatically fed to the sewage. When the second chamber has been filled the precipitation process in the same is started. Simultaneously the liquid flow from the development apparatus is automatically fed to the first chamber which now is empty. When the precipitation process in the second chamber is finished the liquid is pumped through a filter - i.e. for removal of gelatine, silver bromide, etc. - from the second chamber back to the chemicals tank for re-use, whereupon the cycle is repeated.
